The Goodman B1370113 Auxiliary Limit Switch is a genuine OEM 120°F high-temperature safety control for the Goodman GMP075-3 gas furnace. This normally-closed switch monitors temperature at a secondary location in the furnace and opens the control circuit to shut down the burners if it senses an over-temperature condition — protecting the furnace and home from overheating caused by restricted airflow or blower failure.

Trip Temperature: 120°F (auxiliary limit)

OEM vs. Generic

This Goodman OEM limit switch is calibrated to the exact 120°F trip point and mounting footprint specified for the GMP075-3. Generic switches with different trip temperatures or reset behavior can cause nuisance shutdowns or, worse, fail to protect the furnace. For a safety control, always match the OEM specification.

Installation Difficulty

Easy. The switch mounts with a couple of screws and two spade terminals. Shut off power before replacing. Never bypass a limit switch — if the new switch trips repeatedly, diagnose the underlying airflow or blower issue.
